Variables affecting froth flotation can be divided in two groups: chemical and physical. Reagents type and dosages take an important role depending on the ore type. Flotation of fluorite ores typically used tannings to depress calcite and ferrous minerals, starch and/or dextrin to depress quartz and a fatty acid collector [8,[16], [17], [18]].
